Целью данного исследования является получение сорбентов из коры лиственницы путем обработки химическими методами. Проведено сравнение влияния нетоксичных и малотоксичных экстрагентов и реагентов, таких как вода, гексан, этанол и пероксид водорода, на структуру, сорбционные свойства обработанной коры, а также на состав выделяемых экстрактивных веществ. Установлено, что в процессе экстракции коры происходит трансформация основных ее компонентов, что приводит к формированию упорядоченных структур дальнего порядка. Наибольшие структурные изменения наблюдаются для коры, обработанной последовательно этанолом и пероксидом водорода, в основном за счет разложения гемицеллюлоз. Выявлено, что обработка коры таким способом способствует формированию мезопористой структуры. Сорбционная активность обработанной коры по метиленовому синему повышается в 6,5 раз по сравнению с сорбционной активностью исходной коры. Исследования экстрактивных веществ методами ИК-спектроскопии и ГХ-МС показали близкий состав экстрактов коры лиственницы, полученных при водной и этанольной обработках, которые содержат в основном фенольные и спиртовые соединения. Этанол-пероксидный раствор помимо них содержит сложные эфиры и производные карбоновых кислот. Выявлено, что гексановый экстракт коры лиственницы имеет в своем составе в основном терпены и их производные, которые широко применяются в качестве ценных компонентов в медицине и имеют большой потенциал как источник биосырья для зеленых полимеров.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes the structure and sorption activity of larch bark following treatment with green reagents. The aim was to obtain sorbents from larch bark by means of chemical treatment. The study compared the effect of non-toxic and low-toxic extraction agents and reagents, such as water, hexane, ethanol and hydrogen peroxide, on the structure, sorption properties of the treated bark, as well as on the composition of the extracted substances. It was established that the process of bark extraction involves the transformation of its main components, leading to the formation of long-range ordered structures. The greatest structural changes were observed for the bark treated consecutively with ethanol and hydrogen peroxide, mainly due to the decomposition of hemicelluloses. Such treatment of the bark was revealed to contribute to the formation of a mesoporous structure. The methylene blue sorption of the treated bark is 6.5 times higher than that of the original bark. Studies of extracted substances using IR spectroscopy and GC-MS showed a similar composition of larch bark extracts obtained by aqueous and ethanol treatment, which contain mainly phenolic and alcohol compounds. In addition, the ethanol-peroxide solution contains esters and carboxylic acid derivatives. The hexane extract of larch bark was found to contain mainly terpenes and their derivatives, which are widely used as valuable components in medicine and have great potential as a source of biomaterials for green polymers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кора лиственницы</kwd><kwd>экстракция</kwd><kwd>структура</kwd><kwd>состав</kwd><kwd>сорбционная активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>larch bark</kwd><kwd>extraction</kwd><kwd>structure</kwd><kwd>composition</kwd><kwd>sorption activity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность д.х.н.
